Pizza Express: use and reuse in design | 在设计的使用和重用

I had lunch at Pizza Express the other week and noticed that the cutlery were kept on the table in a branded can. At first I thought that the can was specially for that purpose and to convey the brand message.
I passed another Pizza Express restaurant the other day and noticed that they were selling the pizza sauce in the same tins with the same visually attractive design. It is extremely impressive that the packaging design was sufficiently good that the empty tins could be reused in this way.
